Using FMZ Web3 Tools for Blockchain RPC and Smart Contract Calls

Article FMZ guides
Read the original

Summary

This FMZ guide explains how to connect strategies to Ethereum and TRON through configured blockchain RPC nodes and use the platform’s exchange interface for RPC requests and smart contract interaction. It covers ABI registration for nonstandard contract methods, common read and transaction calls, and encoding and decoding contract data. Examples include querying balances and gas estimates, preparing Uniswap-style calls, handling tuples and arrays, and batching TRON contract reads.

The guide also describes switching private keys, signing hashes, and retrieving token data such as decimals and allowances. It is an interface reference rather than a trading strategy: it presents no market hypothesis, backtest, or evidence of profitability. The examples show how to form requests but do not provide a complete operating or security review for a live trading system. Users must supply appropriate node and key configuration and account for chain-specific transaction behavior.

Key ideas

  • FMZ strategies can use configured RPC nodes to query blockchains and interact with contracts.
  • Nonstandard contract methods require registering the relevant ABI before calling them.
  • The interface supports standard ABI encoding, packed encoding, decoding, and handling arrays and tuples.
  • Examples cover Ethereum wallet and gas queries, token methods, Uniswap calls, and batched TRON reads.
  • The guide documents platform mechanics and gives no trading performance evidence.
